Title (EN) METHOD AND SYSTEM FOR HANDLING PDCP OPERATION IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE GESTION D'UNE OPÉRATION PDCP DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) Embodiments herein disclose a method for handling PDCP operation by an EN-DC capable UE in a wireless communication system. The method includes receiving, by an EN-DC capable UE, LTE PDCP PDUs from the LTE RLC entity by a receiver LTE PDCP entity upon re-establishing LTE RLC entity based on the indication that indicates a PDCP version change from a LTE PDCP to a NR PDCP. Further, the method includes processing the LTE PDCP PDUs at the receiver LTE PDCP entity using a LTE format. Further, the method includes reestablishing the receiver LTE PDCP entity and a transmitter LTE PDCP entity of the UE.
(FR) Des modes de réalisation de la présente invention concernent un procédé de gestion d'une opération PDCP par un UE apte à exécuter une EN-DC dans un système de communication sans fil. Le procédé consiste à recevoir, par un UE apte à exécuter une EN-DC, des PDU PDCP LTE, de l'entité RLC LTE par une entité récepteur PDCP LTE lors du ré-établissement d'une entité RLC LTE sur la base de l'indication indiquant un changement de version PDCP d'un PDCP LTE à un PDCP NR. En outre, le procédé consiste à traiter les PDU PDCP LTE, à l'entité récepteur PDCP LTE, à l'aide d'un format LTE. En outre, le procédé consiste à ré-établir l'entité récepteur PDCP LTE et une entité émetteur PDCP LTE de l'UE.
